SPECIFICATION forming part of Letters Patent No. 249,544, dated November15, 1881. Application filed September 17, 18m. (No model.) Patented inEngland March 23, 1881.

To all whom it may concern.-

Beit known that I, GEORGE PRITCHARD, a subject of the Queen of GreatBritain, residing at Seaforth, near Liverpool, in the county ofLancaster, England, have inventedcertain new or Improved FillingMachineryor Apparatus to be used in Making up Packets of PowderedMaterials and other Gommodities forSale, (for which I have receivedLetters Patent in England, No.1,299,-dated 23d March, 1881,) of whichthe followingis a specification.

My invention consists of the construction and combination of the parts,hereinafter described, of machinery or apparatus to be used for fillingat one operation a series of bag-like wrappers or cases with powderedmaterials or other commodities, to be afterward into packets for sale.

The machinery or apparatus constructed according to my inventionconsists, essentially, of a partitioned or divided box open at top andbottom, which box I will hereinafter calltbe mold, and a box made inlongitudinal halves,

the upper half of the box being provided with i a series of conicalfilling-hoppers equalinnumher to the divisions or partitions in the moldIn the partitioned or divided mold described the-bag-like wrappers orcases, openat one end,

are placed, and are heldiu the said mold during the filling,consolidating, folding, or creasing and pressing operations. When thebag-like wrappers are placed in the mold their open ends projectfrom thedivisions in the said mold.

Themold, carryingitls bags, is placed in the. lower half of the dividedbox, before referred to, and the upper half, carrying the filling-hoppers, is arranged on the lower half-box, so that the said hoppers passinto the open ends of the bags placed in the mold. By drawin g thepowdered material into the hoppersthose portions *of the bags bclow'theinner ends of the hoppers are filled with the powdered material, as wellas the hoppers themselves, the spaces between; the hoppers and the upperparts of the bags beingunobcupied by powder.

upper or hopper half of thedividedbox from On lifting the the mold thepowder in thehopperspasses "into the bags up'to a short distance oftheir open months or ends. When the materials may be combined with theupper half made up i used are of a cloggy nature inverted hoppers of thedivided boxthat is to say, the wide ends of the conical hoppers aresituated nndermost. In order to compensate for the varying densities orspecific gravities of the material being 5 used, so asto insure auniform weight of material beingfed to the bags, plates, made byprefcrence of metal of varying thicknesses, are placed as-required inthe bottom of the hopperbox beneath the mold.

I willnow describefwith reference to the accompanying drawings,themanner in which my invention is to be applied. a

A T 1 Fig. 6 represents in longitudinal sectionand r cross-section, and Fig. 7 in plan, the partitioned 'mold a acarrying the bag-like wrappers placed in the divided and hoppered box,ready for filling the bag-like wrappers. The said divided box is made inlongitudinal halves, the

halves being marked respectively d and The upper half, d, of the box isprovidedwith aseries of conical filling-hoppers, e c, equal in num- 0her to the chambers a a in the divided mold a.

-fis the specific-gravity plate at the bottom of the lower half, d ofthe divided box d d?.

This platefis made, byipreferen'ce,.of metal, and can at pleasure bereplaced by others of different thicknesses. By the use of plates f ofdifierent thicknesses the varying densities of the material with whichthe bags are to be filled wrappers are to be filled is of a clo'ggynature.

Itwill beseen, by referring to the drawings, that the wide ends of theconical hoppers e e are situated undermost.

V Fig. 9 represents in plan, and Figs. 10 and 11 in cross-section, thefilling-table, which I use with the divided or divisioned mold a a andthe divided box d d and its hoppers '0 e, the said mold containing theseries of bag-like wrappers c c which have been filled with the powderedmaterial in the manner hereinafter explained. The section Fig. 10 istaken on thel-ine a0 .70, Fig. 9, and the section Fig. 11 is takenon theline 3 y, Fig. 9. The said Figs. 9, 10,arrd 11 are drawn to a smallerscale than Figs. 1, 2, 3, 4, 5, 6, and 7. Y

The table 9 is inclined at its back h, where the material with -\\'.hichthe bags are to be filled -is stationed. The said table gis furnishedwith a well 'or' depression at t'of a size proper to receive thedivided-box d d and its mold. Jointed to one side-of the 'saidtable is aThe said 'stay or leaf 5 stay or holding-leaf, g g? has the angularfigure represented, and is capableof being turned down into thehorilines in Fig. 11. to'embrace or inclose two sides of the'divided box(H1 and thus secure the said box and its The said stay or: leaf g alsoforms an extension of the table!)- contents in the well at 'i.

at the front and end of the divided box d d The divided box 01 d issupported in the well i by Tapiece's carried by the cross-bars 7c 70,

(see Fig. 11,) and when so supported the open tops of the hoppers e e ofthe divided box are on the same level -as the horizontal part 9 of thefilling-table :and its stay or leaf 9 as seen in Fig. 10.

I will now describe the manner in which the filling is effected.

Theemptybag-like wrapperscch-avingbeen placed in the divided orpartitioned .mold a a so that their open ends projectfrom the divisionsor chambers a 'therein, as represented in Fig. 4-, thesa-idfilled moldis-placed in the lower half, d ,of the divided box-(1:61 Fig. 5,

the said mold resting upon the specific-gravity plate f, as represented:in- Fig.6. The up-.

per'or hopper half, 01, of the divided box-d d is next arranged on thelower half-box, (1 as represented in the said Fig.6,"the several h'op-.pers'e e passing more or. less into the open ends-of the-bags torwrappers c c, placedin the mold-,accordin g to the thickness;-ofthe-specificgravitycplate f used. The divided box d (P,

oontainingthe mold a (W, with its empty baglike wrappers or cases 0 0,Figs. 6 and 7, is

next transferred to the filling-table, (represented in Figs. 9, 10, and11,) and placed in the well i in the said table, and fixed in its placeby turning down the hinged stay or holding leaf 9 as shown in the saidFigs. 9, 10, and 11. The'bags are now ready to be filled. This isefiected by the attendant drawing the powdered material by means of thedraw-bar or scraper-bar I from the store at m onto the horizontal part gof the table, and from thence into the hoppers e 0 until the bags 0 cand the said hoppers are filled with the powdered ma- 'terial. It willbe seen by an examination of the sections, Figs. 10 and 11, that thepowdered material does not fill the spaces between the hoppers and theupper parts of the bags, so that when the upper or hopper half, d, ofthe divided box d d is lifted from the mold a the powderin the saidhoppers passes into the bagsup to ashort distance-of their-open monthsor ends. The powder in the hoppers is thus used to complete thefilling'of'the bags to the required height. 111 this way the bags arefilled with a measured quantity of the powder, the varying densities ofthe material which is to be measured being compen sated forby chan ging,as required, the specific-gravity platef, as before described, and thusincreasing or diminishing the spaces between the hoppers and I theuppe'rparts of the'bags which are-not filled zontalxp'osition represented, orof being raised 1 into the vertical positionindicated in dotted Whenshut down it is made i with the material. Although for convenience ofdescription I have only described my invention as applied to the makingup of powdered materials for sale,yet I wish itto be understood'that'mysaid invention is equally applicable to the making up for sale of othercommodities, such as sugar, tea, seeds, and the like; but I do not,however, limit the use of my invention to any particular material.

Having now described the nature of my invention and the manner in whichthe same'is to be carried into effect, what I claim is- 1.
